Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of either
lung infection (
pneumonia) or
bronchitis is more.
You have completed antibiotic course but still having symptoms, so better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest
x ray 3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out lung infection.
PFT is must for the diagnosis of bronchitis. It will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid (ICS).
So better to first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
